Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to an elevating bed with a cord reel that makes effective use of indoor space.

<Prior Art> In recent years, housing conditions have been severe, and furniture placement to effectively utilize narrow rooms has been seriously considered. This is particularly problematic when using a bed in a small room. For example, in the old days, one end of the bed body was pivoted to the wall.
There is a known type in which the bed is rotated 90 degrees to stand up and stored on the wall when not in use. With this cot with a flip-up mechanism, the bedclothes shift when not in use, making it troublesome to set up and use, and for this reason, it has not become very popular. In order to eliminate this drawback, JP-A-6
A mechanism, such as the electric elevating bed shown in Publication No. 2-249614, in which a single bed I' is supported by elevating wires at fixed guide rail positions that are erected on all sides, and is horizontally raised to the ceiling position when not in use. Storage types have also been developed.

<Problem that the invention seeks to solve> However, even in this case, there are problems.

For example, the bed itself, which can be raised and lowered, must be connected to a power cord for the electric appliances such as the drive motor for raising and lowering the bed, and the lighting equipment installed on the back ceiling (bottom side) of the bed. When the bed is laid down to qt along the fixed rail, the power cord, which is located on the fixed rail, does not follow the rise and fall of the bed and becomes loose, which is exposed to the outside and looks unsightly. .

In view of the above-mentioned circumstances, the present invention has a structure in which the power cord is wound up behind the ceiling or on the bed side, and by interposing 11 cords between the suspension belt and the fixed rail, the present invention solves the above-mentioned problem. The purpose is to provide the following.

The present invention provides a bed device in which a bed suspended by a belt using a vertical fixed rail as a guide is moved up and down by winding and unwinding the belt using a motor. Install electrical appliances such as lighting fixtures, and wrap the electric wire cord between the fixed rail and the belt around the cord reel installed behind the ceiling of the room or on the side of the bed, so that even if the bed moves up and down, the power cord will not loosen. It was something I lost forever.

Function> Due to the above structure, the belt is wound up or unwound by the drive of the motor provided above the bed on the ceiling side of the room, and the bed is moved up and down. The power cords of electrical appliances, such as lighting fixtures installed in the bed, are dynamically stretched and rewound one degree at a time by a cord reel installed in the ceiling or on the side of the bed. is constantly in a state of tension and never loosens.

Embodiments The present invention will be described below based on drawings of embodiments.

Figures 1 to 4 show an example in which a cord reel for a power cord is installed in the ceiling, and 1 is a fixed rail that is vertical on all sides and whose upper and lower ends are fixed to the ceiling and floor, and is installed in a corner of a room. The bed is located between the two fixed rails 2 and is supported by a suspension belt 3 having a certain width laid in each of the fixed rails 2, and when the bed 1 is in the raised position, an electric appliance is installed on the back ceiling part 1a of the bed that forms the ceiling. A lighting fixture 5 is installed, and a power cord 6 pulled out from the lighting fixture 5 is laid along the predetermined fixed rail 2 and the belt 3 laid in the middle without being exposed to the outside. , (2) The tip of one power cord 6 is wound around a cord reel 7 installed on the back side of the ceiling A, and then connected to a separate power wire (not shown).

In addition, each tip of the belt 3 laid on each of the four fixed rails 2 is wrapped around a pulley (not shown) that is linked to a motor 8 disposed at the upper end of the fixed rail 2 on the ceiling side on the C side, and the motor is It is a mechanism that performs winding and rewinding by four forward and reverse rotations of 8, and the whole becomes an elevating bed 11 with a cord reel. In this case, the guide 4 at the end of the slide arm 1b protruding from the front and rear ends of the bed 1 is fitted into the guide structure 2a of the fixed rail 2, and the belt 3 is placed in a suspended state. Further, at a predetermined position below each fixed rail 3, a lower limit regulating adjuster 9 is attached which has a fully fitting and detachable 11-operation structure.

Reference numeral 12 denotes a knife frame provided around the periphery of the bed 1.

To explain this function, first, when using this elevating bed 11, when it is not in use, the bed 1 is operated by moving the motor 8 located at the top of the bed 1 to the elevating switch 13 attached to the wall of the room or the side of the fixed rail 2. is rotated in the forward direction by appropriately operating the motor 8, each belt 3 (four belts) whose one end is locked on a pulley connected to the motor 8 is wound up, the bed 1 is raised to a position near the ceiling A, and this bottom surface is Ceiling fil! The bed 1 is kept on standby, and the space below the bed 1 is left open to provide an appropriate living space.

Here, when sleeping (when in use), if the lift switch 13 is operated downward, the motor 8 rotates in the opposite direction, the belt 3 rewinds, and the fixed rail 2 of the bed 1 is pulled down, adding 1 layer to the bed 1. When the bed 1 is lowered to a predetermined position, it comes into contact with the buffer material 9a of the adjuster 9 attached to the fixed rail 2 and stops, and the loosening of the belt 3 is detected as appropriate. The motor 8 also stops rotating.Furthermore, since the bed 1 is directly supported by the adjuster, it can withstand the necessary load (human weight).Of course, the adjuster 9 is supported by the buffer receiver. The screw portion 9b at the bottom of the material 9a is attached to the same locking bracket portion 9c to adjust the amount of feeding out and horizontal adjustment.

In this case, stop 1-4 of the bed 1 at the ceiling position is controlled by a limit switch (not shown). 'i
The lower stop is performed by switching a lower detection stage (not shown) that detects slack in the belt 3.

Also,! ! (The power cord 6 of the light fixture 5 is kept under constant tension without loosening due to the tension of an appropriate tension means (for example, using a coil spring attached to this support shaft) provided on the cord reel 7. "One is to follow the feeding of the belt 3. (l, j L
, the installation position of the fixed rail 2 of this power cord 6 is the fifth
As shown in the figure, it may be installed between the belt 3 and the fixed rail 2 in full bloom, or it may be installed in a space 10 within the rail frame different from the belt position of the fixed rail 2 as shown in Fig. 6. The point is that the electric wire cord 6 should not be exposed to the outside in the normal state.

7 and 8 show another embodiment in which a cord reel for winding the power cord is attached to the bed side. That is, the electric wire cord 6 pulled out from the lighting fixture 5 on the back ceiling 1a of the bed 1 is wound -U around the cord reel 7' provided on the bed L side, and the tip of this electric wire cord 6 is inserted into the fixed rail 2 in the same manner as described above. The belt 3 is guided upward along the inside of the laid belt 3, and its end is connected to a power supply wire (not shown) appropriately wired on the back side of the ceiling A.

In this case, when the bed 1 is moving downward, the power cord 6
The cords are sequentially let out from the cord reel 7' and placed in the fixed rail 2, where they are stretched in a straight line. In addition, bed 1 which is not in use
During the upward movement of the cord reel 7', the winding action of a coil spring (not shown) on the support shaft of the cord reel 7' prevents the fixed rail 2 from becoming slack due to the continuous winding on the cord reel 7'. .

In the above embodiment, the electric appliance was explained as a lighting fixture installed in the ceiling behind the bed, but the same applies to the installation of other electric appliances such as audio equipment, and the installation position may be anywhere as long as it is in the bed. .

<Effects of the Invention> As described above, the cord rail-equipped ascending bed of the present invention is equipped with a lighting equipment provided in the bed section and an electric appliance dedicated to audio equipment.
Wrap the power cord of the wiring around the cord reel installed on the bed side 1 unit or the back side of the top unit, and place the intermediate guide of the power cord in the fixed rail that serves as a support and on the back side of the bed suspension belt. By running the power cord along the side, the power cord after set is completely invisible from the outside and does not spoil the interior scenery, allowing it to be placed on the moving body (bed body) on the third floor! This has the effect of making it easier and more reliable to attach electrical appliances.
